Stateful NAT64: Network Address and Protocol Translation from IPv6 Clients to IPv4 Servers (RFC )

To put it simply, NAT64 is considered a transition tool for IPv4 and IPv6 network addressing. Just like Network Address Translation (NAT) ...

A public IPv4 address is shared among several IPv6-only clients. To accomplish this, NAT64 translates incoming IPv6 packets into IPv4 and vice versa. This ...

ipv4 主动访问 ipv6 ：配置 ipv6 前缀，配置 nat64 静态映射，类似 nat server 原理. ipv6 主动访问 ipv4 ：配置 ipv6 前缀，做 nat64 policy ，类似 nat outbound 原理。. 目前 ipv6 多数用在局域网，然后在网关做 nat64 出去变成 ipv4 ，也有做隧道出去的，也就是说一般运营商的骨干网都不支持 ipv6 ，除非运营商明确已经 ...

NAT64是一种通过网络地址转换（NAT）的形式促成IPv6与IPv4主机间通信的IPv6过渡机制。NAT64网关是IPv4与IPv6协议间的转换器， 它需要至少一个IPv4地址和一个包含32位地址空间的IPv6网段。为该服务保留的“知名前缀”是64:ff9b::/96。 IPv6客户端将希望与之通信的IPv4地址嵌入在IPv6网段的主机部分，构成一个嵌入IPv4的IPv6地址（IPv6网段中的32位地址空间），并将数据包发往生成的地址。NAT64网关则创建IPv6与IPv4地 …

NAT64 is an IPv6 transition mechanism that facilitates communication between IPv6 and IPv4 hosts by using a form of network address translation (NAT). The NAT64 gateway is a translator between IPv4 and IPv6 protocols, for which function it needs at least one IPv4 address and an IPv6 network segment comprising a 32-bit address space.

If you have IPv6 and don't want to hassle with IPv4 and NAT yourself, you are free to use my public NAT64 service. The rental costs for the current hosting is quite affordable for me. If that becomes insufficient I will look for partnerships with transit providers who are able to make a little profit from carrying parts of the traffic.

For IPv6 only customers without IPv4 connectivity, we provide DNS64 resolvers and NAT64 routers to provide IPv4 connectivity. Please note, applications must be ...

27.04.2012 · Network Address Translation IPv6 to IPv4, or NAT64, technology facilitates communication between IPv6-only and IPv4-only hosts and networks (whether in a transit, an access, or an edge network). This solution allows both enterprises and ISPs to accelerate IPv6 adoption while simultaneously handling IPv4 address depletion.

Apr 27, 2012 · Network Address Translation IPv6 to IPv4, or NAT64, technology facilitates communication between IPv6-only and IPv4-only hosts and networks (whether in a transit, an access, or an edge network). This solution allows both enterprises and ISPs to accelerate IPv6 adoption while simultaneously handling IPv4 address depletion.

NAT64 is a mechanism for IPv4-to-IPv6 transition and IPv4-IPv6 coexistence. Together with DNS64, the primary purpose of NAT64 is to allow an ...

今天我们来了解下 NAT64协议概述。NAT（NetworkAddress Translation，网络地址转换）是1994年提出的。当在专用网内部的一些主机本来已经分配到了本地IP地址，但现在又想和因特网上的主机通信时，可使用NAT方法。定…

nat64自定义前缀 无论是 IPv4转换地址 还是 IPv6可翻译地址 ，都采用相同的内嵌地址格式。 可自定义的前缀长度仅能在32、40、48、56、64、96位中选择，每种前缀长度的格式如下图所示：

22.07.2020 · NAT64-prefix::0808:0808 (8.8.8.8 via Cisco ASA NAT64) NAT64-prefix::0808:0404 (8.8.4.4 via Cisco ASA NAT64) This routes queries to Google Public DNS through the Cisco ASA NAT64. With some additional Cisco ASA configuration, AAAA queries are translated into A queries, and A responses are translated back into AAAA with the configured prefix.

NAT64 is an IPv6 transition mechanism that facilitates communication between IPv6 and IPv4 hosts by using a form of network address translation (NAT). The NAT64 gateway is a translator between IPv4 and IPv6 protocols, for which function it needs at least one IPv4 address and an IPv6 network segment comprising a 32-bit address space. The "well-known prefix" reserved for this service is 64:ff9b::/96.

Using a NAT64 gateway with IPv4-IPv6 translation capability lets IPv6-only clients connect to IPv4-only services via synthetic IPv6 addresses starting with a ...
